its Rishenj m8 , btw i didn't tried yet any good media or any 8x media so plz help me guys , i just need to know where is is prob :S !!!! btw , i'v updated my drive to different firmware ( t4s5 , bsok , t4s9...) and still didn't work , i can still burn them and my drive(w512g) can't read them while they are readable on other devices

Well mate that's a serious problem indeed. I've used Princo's in my NEC 3500 Plextor 708 and Pioneer too, NEVER succeeded to read them correctly, NOT A SINGLE ONE! There are cheaper media with far more quality than them, I don't understand why they sell that make

Unfortunately Taiyo Yuden is a little bit hard to find in some countries, don't you agree? I've encountered some fake TY's in the market though, mainly sold as Bulk w/o logo, or with a false TYG02 media ID (Budget), with the quality on the reverse side of course. Better be cautious

Anyway, I use TY for important data, never had a single problem, I highly recommend them too!

An0nym0us.......Princo DVDs are like Cow poop. You can't do much with them other than Burn them when they dry out. At least you can use cow poop in your flower beds, and princos are not even any good for that. Buy some of the Sony DVDs, even thier worst is still good. No more Princos unless you like to throw away money. OK
